It has been a while but I'm updating Nuxstr while working out some proof of concepts: https://nuxstr.nostrver.se/

I'm also exploring how we could execute a so called 'check-in' at a place (signing a kind 13811 event) in a same way we did with Foursquare back in the days (a blast from the past here: https://piped.r4fo.com/watch?v=4OUBG3v5ZvU)
